[ovirt-users] Ovirt python API clone VM to other data domain

[Algirdas Žemaitis]

Thank you, this was the solution, 
Modified version of original script available here: http://pastebin.com/GEtSJMCN
Original : https://github.com/wefixit-AT/oVirtBackup

Diff: moded version is doing backup for all running VMS in cluster, trying to clone VM into different storage domain (avoiding load on main domain)
Please remove "iterration" if statement, I was using it to stop script from doing backup for all VMs (testing)
